Climate-protection by the tonne - thanks to maximised energy-efficiency Steel is 100% recyclable. But that's not all. Efficient utilisation of the waste heat yielded in the production and processing of steel saves many tonnes of emissions every year in the GMH group's plants. Here two examples from the Georgsmarienhütte GmbH steel mill and the Gröditz forging plants.

Next-generation con-rod steels GMH Gruppe has long been the reliable partner of the automotive industry. Our con-rod steels, for example, are noted for their high mechanical strength and excellent crackability. Despite these high achievements, our development teams saw no reason to rest on their laurels: a new generation of even further enhanced steels is already available.

Connecting rods: 10% lighter thanks to new material 28 grams make a world of difference in automotive engineering. Using the GMH group's innovative 46MnVS5 material, they can be saved on crack connecting rods. This makes this new grade of steel the reliable solution in lightweighting – and the ideal candidate for parts such as connecting rods in the higher performance categories.

Innovative waste-gas routing boosts plant efficiency The electric arc furnace (EAF) is the central element in steelmaking at Georgsmarienhütte GmbH - in exactly the way that improvements to processes and technologies are a central topic within the GMH group. When these two meet, the results are things, such as an innovative waste-gas routing, that improve even further tried-and-tested facilities such as our furnace.

Innovative burners make production of secondary steel more energy-efficient Technology experts of GMH Gruppe work with partners in a joint research project aimed at reducing the carbon footprint of secondary steel production by means of a new burner concept and future use of hydrogen to replace fossil fuels in steel melting. The hydrogen technology offensive started as early as last year with the OptiLBO project.
